Delete a Single Link from a Simulink Object
If you have an obsolete link to a requirement, delete it from the model object.
To delete a single link to a requirement from a Simulink model object:
1
Right-click a model object and select Requirements Traceability > Open Link
Editor.
2
In the top-most pane of the Link Editor, select the link that you want to delete.
3
Click Delete.
4
Click Apply or OK to complete the deletion.
Delete All Links from a Simulink Object
To delete all links to requirements from a Simulink model object:
1
Right-click the model object and select Requirements Traceability > Delete All
Links
2
Click OK to confirm the deletion.
This action deletes all requirements at the top level of the object. For example, if you
delete requirements for a subsystem, this action does not delete any requirements
for objects inside the subsystem; it only deletes requirements for the subsystem
itself. To delete requirements for child objects inside a subsystem, Model block, or
Stateflow chart, you must navigate to each child object and perform these steps for
each object from which you want to delete requirements.
